Computing Performance

When the number of arrays increases, the triangular systolic array for QR decomposition of the received data matrix has an increasing significantly hardware resource consumption. In order to reduce the hardware cost, the triangular systolic array (TSA) architecture could be modified into a multiplexing architecture called MQRD which could call the same module at the different time. Then MQRD was designed and simulated on the software ISE. More, MQRD was added to the adaptive beanforming system to study its computing performance. The results showed that MQRD not only kept the numerical stability and scaled well, but also reduced the hardware resource cost efficiently. Theoretical analysis and simulation results show that MQRD can reduce hardware cost efficiently. So, MQRD is a better choice than TSA in the multi-antenna system.
